A series of single-phase white-emitting phosphors Ba 3 Bi(PO 4 ) 3 (BBP):8 at.% Dy, x at.% Eu were successfully synthesized through high temperature solid-phase method. The luminescence properties of BBP:8 at.% Dy, x at.% Eu were systematically investigated. Experimental results indicate the doping of Eu 3+ ions can effectively compensate the red light component in the emission spectrum and tune the correlated color temperature of BBP:8 at.% Dy, x at.% Eu from cool white light (5097 K) to warm white light (3661 K). Moreover, BBP:8 at.% Dy 3+ , 0.8 at.% Eu 3+ phosphor exhibits excellent thermal stability and the fluorescence intensity at 150 °C can still maintain 76% of that at 25 °C, while the activation energy is determined to be ~ 0.23 eV. In addition, the quantum efficiency of BBP:8 at.% Dy 3+ , 0.8 at.% Eu 3+ phosphor were measured to be 61%. These results suggest that BBP:8 at.% Dy 3+ , 0.8 at.% Eu 3+ can be a NUV-pumped single-phase white phosphors with excellent comprehensive performances.

Gold nanoparticles (AuNPs) were prepared by a solvothermal method using sodium alginate (SA) as both, the reductant and stabilizer . The formation of SA-AuNPs was confirmed by UV–Vis spectroscopy, transmission electron microscopy , X-ray diffractometry, and X-ray photoelectron spectroscopy . SA-AuNPs were functionalized with fluorescent 3-(dansylamino)phenylboronic acid (DAPB) moieties, through interactions between boronic acids and diol groups. The fluorescence resonance energy transfer from DAPB to AuNPs quenched the fluorescence of DAPB. In the presence of glucose, the competitive binding of DAPB with glucose resulted in the release of assembled DAPB from the surface of SA-AuNPs, resulting in the increase in fluorescence intensity . Furthermore, catalytic reduction of 4-nitrophenol was monitored via spectrophotometry using DAPB functionalized SA-AuNPs probes as catalyst. Compared to SA-AuNPs, the nanoprobes exhibited higher catalytic rates.

In order to explore the corrosion inhibition mechanism of 1-vinyl-3-hexylimidazolium iodide with different concentration for mild steel in 0.5M H 2 SO 4 at 298K, experimental and theoretical studies were carried out. Not only weight loss but also electrochemical experiments reveal that 1-vinyl-3-hexylimidazolium iodide ([VHIM]I) has higher inhibition efficiency. And all experiments have good consistency. The inhibition efficiency was more than 96% comparing with the blank when the concentration was 5mM. It indicates that [VHIM]I adsorbed on the surface of invested metal by forming a film to protect metal. In addition, SEM observation and ATR-IR spectra was used to further confirmed the above. The Langmuir adsorption isotherm was the most proper adsorption model for the adsorption of [VHIM]I molecule on mild steel surface. Moreover, theoretical calculation and molecular dynamic (MD) simulation also manifest that [VHIM]I was absorbed mightily on the metal surface in a parallel mode.

Pseudocapacitor electrode materials, such as transition metal oxides/sulfides, have been extensively investigated and shown to have fast energy storage properties, but their low rate performance and poor cycle stability are serious problems in practical applications. We present here a design for the architecture of these electrode materials with the aim of improving the rate performance and cycle stability of pseudocapacitors by using an interface ion-exchange method. Precursor materials obtained by a hydrothermal reaction were soaked in aqueous NaHS solution to synthesize the urchin-like core–shell structure of NiCo2(CO3)1.5(OH)3@NiCo2S4. Such core–shell nanostructure electrode materials can make full use of both components with synergistic effects. Excellent results were obtained with a capacitance of 956.4 F g−1 at a current density of 4 A g−1 in the three-electrode system and an actual energy density of 32.3 W h kg−1 and power density of 1835 W kg−1 in the asymmetrical supercapacitor.

Currently, the both low electronic and ionic conductivity have seriously hindered the further application of Na 3 V 2 (PO 4 ) 3 (NVP). Nevertheless, traditional carbon materials modification only improves the electronic conductive property, rather than modifying the ionic conductivity. Herein, N-rich carbon resources of glycine (GLY) is introduced to synthesize NVP, which can act as reducing agent and morphology inducer to optimize NVP sample. Notably, GLY supplies favorable N-doped carbon skeleton, and this defective carbon structure benefits for the accelerated electronic conductivity. Besides, porous construction is established after introducing GLY. This unique morphology significantly improves the infiltration effects of electrolyte, thus providing more electrochemical active sites for Na + de-intercalation to improve the ionic conductivity. Meanwhile, porous framework supplies enough space for the shrinkage of crystal cells, so the stress-strain effect is highly restrained, which is demonstrated by Ex-situ XRD. The stabilized crystal and morphological structure of NVP@GLY-2 has been verified by after-cycled XRD/SEM/XPS. Highly improved kinetic characteristics are also investigated by In-situ EIS. Moreover, Accelerating Rate Calorimeter (ARC) measurements indicate that NVP@GLY-2-based half and full cells also have excellent thermal safety properties. Comprehensively, NVP@GLY-2 reveals a high capacity of 119 mAh g −1 at 0.1 C. It reveals 84.5 and 71.2 mAh g −1 at 10 and 50 C, with capacity retention rates of 88.9 % and 85.8 % after 1000 cycles.

A novel MIL-101(Fe)/Bi₂S₃ Z-scheme heterojunction with a metal–organic framework (MOF) structure was synthesized via a solvothermal method. Compared with pristine MIL-101(Fe) and pristine Bi₂S₃, this composite exhibits a significant breakthrough in degradation performance toward rhodamine B (RhB) and tetracycline hydrochloride (TCH). Specifically, it achieves a degradation efficiency of 95.7% for 20 mg/L TCH within 120 min and 98.6% for 40 mg/L RhB within 90 min.Characterizations including X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet–visible diffuse reflectance spectroscopy (UV–Vis DRS), and electrochemical impedance spectroscopy (EIS) confirm that the MOF structure of MIL-101(Fe) provides a stable support matrix for Bi₂S₃. Moreover, the construction of the Z-scheme heterojunction can effectively suppress the recombination of photogenerated electron–hole pairs while retaining the strongly oxidizing hydroxyl radicals (・OH) and strongly reducing superoxide radicals (・O₂⁻). More importantly, after five recycling cycles, the degradation efficiencies of the composite for TCH and RhB remain at 86.8% and 88.6%, respectively, with no obvious damage to its crystal structure after cycling. This demonstrates superior structural stability and reusability compared to most reported MOF-based photo-Fenton catalysts.

By utilizing the in situ polymerization reaction of o-tolidine and p-phthalaldehyde, magnetic inorganic/organic hybrid materials were synthesized. Various characterization techniques were employed to analyze the morphology and phase composition of the materials. Using Rhodamine B as a characteristic pollutant, it was found that the maximum adsorption capacity of the materials reached 171.59 mg/g. Density functional theory (DFT) calculations were conducted on different adsorption configurations, revealing that the adsorption process is primarily dominated by π–π interactions, alongside electrostatic attraction and donor–acceptor interactions. This provides a theoretical basis for the subsequent design and preparation of more efficient adsorption materials.

C18-modified bipyridinium-functionalized silica was prepared and further modified with tetras(4-sulfonatophenyl)styrene (TPE-SO 3 H) via ion bonding. Thus, two novel stationary phases, including C18-modified bipyridinium stationary phase (Sil-DPC18) and TPE-SO 3 H-functionalized C18-modified bipyridinium stationary phase (Sil-DPC18-TPES) were obtained. The stationary phases were characterized by elemental analysis and Fourier transform infrared spectroscopy (FT-IR). The reversed-phase chromatographic performance of Sil-DPC18 and Sil-DPC18-TPES were evaluated using the Tanaka test mixture, alkylbenzenes, and linear polycyclic aromatic hydrocarbons (PAHs). Compared to an in-house Sil-C18, Sil-DPC18-TPES and Sil-DPC18 exhibited stronger aromatic selectivity and shape selectivity, but weaker hydrophobicity and hydrophobic selectivity. Furthermore, Sil-DPC18-TPES demonstrated better hydrophobicity, hydrophobic selectivity, aromatic selectivity and shape selectivity compared to Sil-DPC18. The enhancement could be due to the introduction of TPE-SO 3 H. In addition, Sil-DPC18-TPES and Sil-DPC18 exhibited good separation selectivity for PAHs, phenylesters, phenols, and phenylamines compared to Sil-C18.

Intraluminal drug coated devices, such as paclitaxel (PTX)-coated balloons, are commonly used to treat arterial occlusive diseases caused by atherosclerosis. However, their efficacy is limited by drug loss, poor drug retention, insufficient penetration and high costs. Nanoparticles with molecular targeting capabilities offer a promising solution to these challenges. Collagen hybridizing peptide (CHP) specifically binds to degraded collagen in atherosclerotic plaques, enabling precise molecular imaging and targeted therapy. In this study, we demonstrated that collagen degradation was significantly elevated in atherosclerotic plaques and could be effectively identified by CHP in both atherosclerosis patients and mice models. Using the emerging copper-free click chemistry reaction, we functionalized the widely used albumin-based indocyanine green nanoparticles and albumin-bound paclitaxel nanoparticles with CHP, developing a targeted nanoplatform for molecular imaging and therapy. In vivo photoacoustic (PA) imaging and ex vivo fluorescence (FL) imaging revealed significantly enhanced PA and FL signals in carotid artery and aorta plaques with CHP functionalized nanoparticles engaging. Furthermore, therapeutic evaluations showed that CHP significantly improved the plaque-targeting capability of albumin-bound paclitaxel nanoparticles, thereby enhancing their therapeutic efficacy against atherosclerotic plaques. These findings highlighted CHP-functionalized albumin nanoparticles as a promising strategy for precise and effective atherosclerosis molecular imaging and treatment. Graphical Albumin nanoparticles functionalized with CHP by copper-free click chemistry reaction, enhancing the imaging ability and therapeutic efficacy for atherosclerosis by elevated plaque targeting capability.

Ultra-stable copper nanoclusters were fabricated for the sensitive determination of cholesterol based on fluorescence turn-off. Red-emitting copper nanoclusters capped with cysteine were first synthesized with a short storage time (15 d). Then, the addition of chitosan and the adjustment of media pH were applied to modulate the unstable clusters into exceptionally stable aggregates with cyan-green emission possessing a long lifetime over 180 days. The aggregation-induced emission (AIE) of chitosan-modified copper nanoclusters (Cys-CuNCs) can be significantly quenched by cholesterol due to the interaction between cholesterol and chitosan. The fluorescence response of Cys-CuNCs to cholesterol exhibits a rapid equilibrium (1 min), high sensitivity with a detection limit of 19.63 μmol·L⁻ 1 (3σ, n = 3), and a wide linear concentration range of 25.0 ~ 1000.0 μmol·L⁻ 1 . The proposed method has good stability and can be employed for cholesterol determination in biofluids. Graphical

Titanium niobium oxide (TiNb 2 O 7 , TNO) has become a high-performance anode material for fast-charging lithium-ion batteries due to its high specific capacity, safety advantages and stable cycling performance. Nevertheless, the material’s low electronic/ionic conductivity remains a critical challenge for commercial implementation. The present study presents a novel Ni-doping strategy for TNO that optimizes the electronic structure, achieving a remarkable improvement in lithium-ion storage performance through enhanced charge transfer and ionic diffusion. The Ni 0.02 -TNO anode exhibits a reversible capacity of 240.7 mAh g −1 after 150 cycles at 1C, while retaining 172.9 mAh g −1 even after 1000 cycles under an ultra-high rate of 10C, demonstrating exceptional long-term stability and rate capability. Furthermore, the assembled LiFePO 4 (LFP) ||Ni 0.02 -TNO pouch cell demonstrates outstanding cycling stability, with 86.9% capacity retention over 500 cycles at 1C. Density functional theory calculations reveal that Ni doping reduces the bandgap from 2.193 eV to 0.765 eV, thereby enhancing electronic conductivity and facilitating faster charge transfer kinetics. This work provides a viable pathway for designing advanced lithium-ion batteries with rapid-charging capability and long-term cyclability.

Uranium (U) is essential for the nuclear power industry and plays an important role in decarbonizing the energy supply. However, concern regarding the sustainability of U supply is growing, as conventional U ore reserves are scarce and common mining practices have a notable environmental footprint. Exploring alternative U sources and developing sustainable extraction methods are therefore desired. Here we show a spontaneous U extraction strategy based on droplet falling. Specifically, naturally falling salt-lake water droplets interact with a film of aluminium–fluorinated ethylene propylene–chitosan coated on carbon felt, converting mechanical energy into electricity and driving an in situ electrochemical process for spontaneous U extraction. Electrons released at the solid–liquid interface on a superhydrophobic fluorinated ethylene propylene surface reduce U(VI) adsorbed by chitosan to U(IV), ultimately forming U(VI) precipitates. Field experiments conducted in real salt-lake environments with high salinity confirm the scalability and robustness of droplet U extraction, yielding magnesium uranate (MgU 2 O 7 ) and sodium polyuranate (Na 2 U 7 O 22 ) as the main products. A multistep device reduces the U concentration of salt-lake water from 173 μg l −1 to 34 μg l −1 (extraction efficiency of 80.3%) with minimal extraction of co-existing ions. Overall, this work offers a viable pathway to sustainable U resource extraction.
